copied!<p>I'm trying to make a poll with Django but I'm very new to it and when I go to the admin thing it gives this error:</p> <pre><code>ImproperlyConfigured at /admin/polls/poll/1/ 'PollAdmin.fields' refers to field 'None' that is missing from the form. </code></pre> <p>I'm not very sure what that means but this is my admin.py file which I think is causing the error:</p> <pre><code>from django.contrib import admin from polls.models import Poll class PollAdmin(admin.ModelAdmin): fields = [ (None, {'fields': ['question']}), ('Date information', {'fields': ['pub date']}), admin.site.register(Poll, PollAdmin) </code></pre> <p><strong>Edit</strong>:</p> <p>Here's my models file if that matters:</p> <pre><code>from django.db import models import datetime from django.utils import timezone class Poll(models.Model): question = models.CharField(max_length = 200) pub_date = models.DateTimeField('date published') def __unicode__(self): return self.question def was_published_recently(self): return self.pub_date >= timezone.now() - datetime.timedelta(days = 1) class Choice(models.Model): poll = models.ForeignKey(Poll) choice_text = models.CharField(max_length = 200) votes = models.IntegerField() def __unicode__(self): return self.choice_text </code></pre> <p><strong>Edit (again)</strong></p> <p>Now I fixed my PollAdmin class to this:</p> <pre><code>class PollAdmin(admin.ModelAdmin): fieldsets = [ (None, {'fields': ['question']}), ('Date information', {'fields': ['pub_date']}), ] </code></pre> <p>But it's saying:</p> <pre><code>DoesNotExist at /admin/polls/poll/1/ Site matching query does not exist. </code></pre>
